In Korean it's paegopa, which literally means "Stomach is empty". My mother tongue is Telugu we have two words to describe this, and one of them is "stomach is empty".

Italian and French use the same grammar as Spanish for that expression ("j'ai faim" in French for example). Interestingly, Romanian, which is often the odd one out among Romance languages with its rather unusual grammar, does not use that form and instead says "mi-e foame" (a shortening of "îmi este foame"), which could be translated literally word for word as "to me is hunger", a rather odd dative-reflexive grammatical construct for a Romance language but actually not that strange if you know German or Russian.

"Estoy con hambre" is a valid way to say that you're hungry in Spanish too btw. It's an unusual way to phrase it but it's totally fine.

Come to think of it, it's interesting that in English you say that you ARE hungry whereas in Spanish you say that you HAVE hunger. I guess hungriness is an innate characteristic for gringos but merely a status effect for hispanics.
